Abstract
The propagation of a plane heating and ionization wave through a gas is considered; the wave is sustained by a strong flow of monochromatic optical radiation (traveling in the opposite direction) through energy transfer attributable to the emission of a continuous spectrum. In the range of radiation flux densities under consideration, a situation arises in which the expanding hot layer generates a shock wave transparent to the incident radiation. The radiation wave is subsonic. The pressure within the hot layer is smoothly distributed, so that its parameters may be determined by considering the equations of energy and transport of the monochromatic source radiation and the radiative-transfer equations for various frequencies and directions. The true spectral composition and distribution of the radiation are considered in detail, using refined tables of the thermodynamic and optical properties. The results of numerical calculations relating to air are presented; so are certain details of the methods used in averaging the transfer equations, which prove very efficient for the radiation-gasdynamic problem under consideration and greatly reduce the volume of calculations.
